Disabling IRQ 16

Hi list, I’ve a problem with my system on CentOS 6.5 x86_64 on a workstation.

During utilizzation, after several hours after boot (6/7 hours) I get an error:

Disabling IRQ #16

and after this seems be that 3d acceleration is unloaded.

This is a workstation with a dedicated vga (nvidia gt450) and 3 nics. This problem started when I’ve plugged the third nic. Without third nic all works very good.

from /proc/interrupt:

16: 110 647 64858 0 0 0
0 0 IO-APIC-fasteoi ehci_hcd:usb1, ahci, eth3, nvidia

I’ve tried to boot the system with irqpool without great results. I’ve tried to change my new third gb nic with a fast ethernet 10/100, thinking it was broken but the problem still persists.

I’ve tried to replace my vga card with another, the problem still persists.

From dmesg I get:

Disabling IRQ #16

I’ve inserted the third nic for channel bonding.

What I can try to avoid this error? It’s an hardware problem on mobo?

Any hints will be good.

Thanks in advance.

One thought on - Disabling IRQ 16

  • Hi Reindl, thanks for the answer.

    I’ve tried to make some hardware changes. I’ve ridden my mobo irq configuration from manual, and changed vga card and nic modo allocation. The problem persist, but now I get for IRQ 19.

    What’s that cause (a condition, an error…) IRQ disabling?

    Thanks in advance.
